Hi @Members_b1CazT1 

The Clear Cache you've heard about is clearing the phone's System Partition Cache Files Section via >

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If o2 supplied the phone then as the merchant they have a Duty of care to support you in the first instance. 

That said Samsung also try to help too. 

Try a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.

If you perform a forum search you may find existing threads with some further help or guidence within.  

A final resort is to back up and factory reset. 

If that does not help then o2 again if they supplied the phone have a Duty of Care under Consumer-Rights-Act-2015. 

A Samsung Experience Store or Samsung Service Centre can also help via https://www.samsung.com/uk/support/repair/ 

If i can be of any further help please don't hesitate to ask  😎

You're very welcome @Members_b1CazT1 

There does appear to be a number of people who have experienced some issues after a software update unfortunately.

Same issue on my Flip 4...was working perfectly until the update, so I don't think it's hardware related.

Main issues I am experiencing is that if I start closing the Flip it already switches off as it reaches the halfway closed position, and then it is unresponsive for at least a few minutes. If it's closed completely and you flip it open the screen remains off and you cannot tap the screen awake or use the side finger reader to open it. Again you have to leave it open and completely flat for a few minutes before trying the fingerprint reader to unlock it again.

Same problem with my flip 4, keeps going off and repeatedly having to press on button. It started immediately after update, tried everything with no luck

My z flip 4 is doing the same thing 3 days after March 2025 update.

It was working perfectly till I started acting weird, first the phone turns off when flipped then the battery is acting crazy, it's going from 0% to 100% then it gets back to it's real percentage despite that the battery protection option was always set to maximum (80%.)

I had this Korean version phone for like a year, It's in perfect condition, not even a scratch and i never dropped it.

I'm surprised about how many people faced this issue after updating their phones.. that's a scam, Z flip series is garbage i don't recommend buying this expensive unreliable phone.

The problem isn't the flex cable. When the screen is off, manually resetting it turns it back on, proving the flex is fine. As identified by a user from Mexico, the issue likely involves the frame magnet and the Hall sensor. To test this yourself: if your phone screen is off when opened, place a magnet near the upper area as demonstrated here:  https://www.youtube.com/watch?v=tiwcjCa4xP0
